Explanation of Responses:

( 1 )This transaction is not a sale of shares by the Reporting Person. Instead, this represents shares that have been withheld by the Issuer to satisfy its income tax and withholding and remittance obligations in connection with the vesting and net settlement of previously reported restricted stock units. ( 2 )On August 31, 2023, the Issuer effected a 1-for-35 reverse stock split (the "Reverse Stock Split") of its outstanding shares of Common Stock. The numbers of shares of Common Stock reported on this Form 4 have been adjusted to reflect the Reverse Split unless otherwise noted. ( 3 )Includes 408 shares purchased on November 15, 2023 under the Heliogen, Inc. 2021 Employee Stock Purchase Plan.

Remarks: The original Form 4, filed on December 19, 2023, is being amended by this Form 4/A to correct the previously reported balances in Item 5 of Table 1. The beginning balance of the number of shares previously reported did not reflect the Reverse Stock Split and has now been adjusted to reflect the Reverse Stock Split.

Reminder: Report on a separate line for each class of securities beneficially owned directly or indirectly.
